4 Claims. 1

This invention relates to door closers of the type generally actuated by springs and adapted to close a door through the medium of levers or arms pivotally connected to one another and secured between the door closer and the door frame, the angular relationship of the arms varying in accordance with the degree of opening of the door. More particularly, the present invention relates to a device adapted for use in conjunction with such types of door closers to arrest and prevent the door closing movement of the arms and thereby cause the door to remain open at a desired degree.

An aim of the invention is to provide a device which will be installable upon a door closer of the type having pivoted arms and which will hold a door open in any desired position for purposes of ventilation or other reasons without the necessity for the use of chocks, wedges, foot stops, or other conventional devices.

A further aim of the invention is to provide a device which can be connected to conventional automatic door closers of the type having arms and which may be actuated mechanically to D- pose the force of the spring urging the arms into door closing movement and thereby to prevent the closing of the door and hold it open in a desired position.

A still further aim of the invention is to provide a simple and effective mechanical device which may be attached to the arms of a conventional door closer of this type and which is easily and quickly operable to freeze" the door at any desired degree of opening, but which will be automatically released from operation by moving the door to a greater degree of opening.

Other objects will be in part obvious and in part pointed out mo'rein detail hereinafter.

The invention accordinglyconsists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

Fig. 10 is a cross sectional detail view taken on line Ill-4 0 of Fig. 8. V

Referring to the drawings, there is illustrated a door closer A of a conventional type which is secured toa door B. The door closer A may be of any suitable type, that shownconsisting of a casing 5 enclosing a spindle 6 driven by a spring (not shown) enclosed in the casing. The casing 5 is generally filled with hydraulic fluid which operates in conjunction with suitable mechanism to cushion the action of the spring upon the spindle in such manner that the door will be gradually returned to closed position. Mechanism may be included which permits a sharp increase in the action of the spring toward the end of the closing movement of the door in order to snap the door shut. A lever or arm I0 is pivoted to the spindle 8 at one end and to a second lever or arm I l at the other end, as at D, the arm ll being secured to the door frame C. The spring in the casing 5 is adapted to urge the arm In in a direction to close the door or, in the present illustrative drawings, in a counterclockwisedirection. The opening and closing of the door changes the angular position of the arms relative to one another and, in particular, as shown by Fig. 3, the arms are forced together by the door closing action of the spring. It is the pur-. pose of our invention to provide means for preventing the arms from coming together and thereby arresting the movement of the door at any point along its arc of travel. Generally, our device consists of a rod :or bar pivotally secured at one end to one arm of the door stop and. adapted to slide freely through a catch member secured to the other arm of the door stop. Me-

chanical meansare provided for engaging the rod and catch member with one another at a desired the arms from coming together.

More particularly, referring to Fig. 1, one emprevent movement of the rod in the direction bodiment of our invention comprises a sleeve [2 shown by the arrow in Fig. 7, or in the door closfirmly secured to one arm ll of a door closer ing direction, and, as in the previous embodias by screws 13.
